Definitions

• This invention relates to winding a strip of sheet material such as a tire component on a spool which is transported to a tire building machine for building a tire.
• the spool may be mounted on a cart which also supports a liner shell for a liner which is interposed between the material wrapped around the wind-up shell of the spool of material.
• apparatus for winding a strip of sheet material on a rotatable spool of sheet material comprising a surface winder having belt means movable into engagement with the strip of sheet material for application to the spool and for rotating the spool characterized by pressure means for moving the surface winder and the belt means toward the spool to urge the strip of sheet material against the spool, and belt drive means engageable with the belt means for delivering the strip of sheet material to the spool and rotating the spool to wind the strip of sheet material on the spool.
• a method of winding a strip of sheet material on a rotatable spool comprising:
• Fig. 1 is an end view of the wind up apparatus embodying the invention showing the surface winder apparatus at the start of the wind up process.
• Fig. 2 is a plan view of the apparatus taken along line 2-2 in Fig. 1.
• Fig. 3 is an end view like Fig. 1 showing the apparatus at the end of the wind up process.
• Fig. 4 is an end view like Fig. 1 showing the apparatus with the surface winder retracted for cart removal.
• a wind-up apparatus 10 having a movable cart frame 12, supported on a floor by wheels 11, for transporting a spool 14 of sheet material 16 from a wind-up position, such as that shown in the drawings, to a delivery or server position spaced from the wind-up position.
• the sheet material 16 is a tire component, such as a tread or ply
• the sheet material may be conveyed to the wind-up position on a belt conveyor 18, where it is carried on a belt 20 to a position spaced from a sheet material applier frame 22 positioned adjacent to the movable cart frame 12.
• the sheet material applier frame 22 has side plates 24 and 26 supporting a driving pulley
• the driving belt 32 is trained around the driving pulley 28, a take-up pulley 34 and a pair of spaced pulleys 36 and 38 of a surface winder 40.
• the take-up pulley 34 may be mounted on pressure controlled air cylinders 35,35 fastened to each of the side plates 24 and 26 with the weight of the take-up pulley and the pressure controlled air cylinders maintaining the driving belt 32 in tension.
• the surface winder 40 has a pressure means such as a pair of piston cylinder assemblies 43 and 44 fastened to the side plate 24 and side plate 26 of the applier frame.
• the piston cylinder assemblies 43 and 44 have piston rods 47 and 48 attached to mounting plates 50 and 52 spaced apart and positioned at opposite ends of the spaced pulley 36 and spaced pulley 38 of the surface winder 40.
• the piston rods 47 and 48 are pivotally mounted to the mounting plate 50 and mounting plate 52 whereby the spaced pulley 36 and spaced pulley 38 are radially movable to conform to the contour of the spool 14. Movement of the surface winder 40 towards the spool 14 is provided by the piston-cylinder assemblies 43 and 44.
• the movable cart frame 12 of the wind-up apparatus 10 may have spaced bearings 58 and 60 for rotatably supporting a shaft 62 of a wind-up shell 64.
• Liner support arms 66 are mounted on the movable frame 12 and extend to a spaced apart position for supporting a liner shell 68 of a liner roll 69 in bearing 70.
• Also supported on the floor are liner support members 71 attached to the movable cart frame at either side thereof for supporting a lead in roller 72, precision guide
• the wind-up apparatus 10 shown in Fig. 3 illustrates the apparatus with the spool 14 at the end of the wind-up operation.
• the wind-up apparatus 10 shown in Fig. 4 illustrates the apparatus with the spool 14 after the sheet material 16 and a liner 78 have been wrapped in a spool which may be transported to another location for delivering the sheet material or for storage.
• the location where the movable cart frame 12 is located, as shown in the drawings, is then open and available for another movable cart frame to be parked, and another spool wound up on an apparatus like that shown in Figs. 1, 2 and 3.
• the diameter of the spool 14 at the beginning of the wind-up operation is the diameter of the wind-up shell 64 as shown in Figs. 1 and 2.
• the diameter of the liner roll 69 on the liner shell 68 is substantially greater than that shown in Fig.
• the surface winder 40 maintains contact with the spool 14, as shown in Fig. 1, so that the spaced pulleys 36 and 38 urge the sheet material 16 on the driving belt 32 against the sheet material into contact with the liner 78 and rotate the spool 14 in a clockwise direction R, as shown in Fig. 1.
• the pivotal mounting of the spaced pulleys on the mounting plates 50 and 52 cause the driving belt 32 to conform with the surface of the spool 14 pressing the material 16 against the surface and at the same time, driving the spool in a clockwise direction. In this condition, the take-up pulley 34 is in a raised position as shown in Fig. 1.
• the driving belt 32 not only carries the sheet material 16 to the spool 14, but also remains in contact with the sheet material as it is applied to the spool. This provides the desired friction for mrning the spool 14 with a controlled pressure from the piston- cylinder assemblies 43 and 44.
• the liner 78 which has one end wrapped around the spool 14, is pulled from the liner shell 68 over the lead in roller 72 through the precision guides 74 and over the lead out roller 76 so that it will be positioned accurately on the spool 14.
